MILL FOR GRINDING GRAIN AND APPLES.

Specification-forming'part of Letters Patent No. 29,490, dated August 7, 1860; Ressued April-19, 1870, Nos. 3,925 and 3,926.

. To all whom itrmag/ concern:

Be it known that I, CHAS. B. HUTCHIN- soN, of Auburn, in the county of Cayuga and State of New York, have invented a new and useful Improvement. in Portable Cider and Grain Mills; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of my invention is to construct a small, cheap, portable machine, adapted to the wants of every farmer and capable of modifications for making cider, grinding grain, corn and cobs and shelling corn with facility. y

My invention consists of a peculiar combination of cider-mill, grain-mill and cornsheller.

In the accompanying drawings: Figure l represents a perspective View of my machine. Fig. Q., is a view of the top of the machine, the parts being partly separated for better illustration. Figs. 3, and et, represent detached pieces hereafter specially to be described.

My machine may be made chiefly of cast iron, the frame A and part of the case B, being cast in one piece and provided with two bearing surfaces for the two wheel shafts C, and D, as represented in Figs. l, and 2, of the accompanying drawings.

In making cider with vmy machine, the apples are fed into' the mill through the hopper H, Fig. 1, and the pomace escapes by the spout G. (The grinding apparatus will be hereafter described.) As the pomace escapes from spout G, it falls directly into the press hoop E. This hoop may be made of wood and strongly bound by iron hoops e. In the lower part of this hoop E, there areaissures 0, for the escape of the cider. The bed K, of the press is supported by the cross bar A of the frame A and is provided with a groove and spout for conducting away the cider in the usual manner. The follower'of the press is drawn downward by means of the screw shaft F which runs in a female screw in the part B of the case, which, as above mentioned, is cast in the same piece with the frame A.

a smallquantity of new cider may be made,

vand thus sweet cider be always at command.

ence of this wheel is seen upon the grinding surface, a common mill dress, M', the dress being cast in the iron. Between this mill dress and the shaft C the Wheel is armed with a series of teeth m, of very .peculiar form, as represented in Figs. 2 and Ll. These long hooked teeth are intended for crushing apples or cracking cobs, while the mill dress M is designed for liner grinding, either of apples or cobs, or, when the mill is set closely, for grinding various kinds of grain. In the removable portion N, Fig. 3, of the case, is another extraordinary, yet different grinding surface, intended to oppose the grinding surface upon the wheel M, Fig. 3. This other surface is represented in Fig. 3, the wheel N (with the hopper H, which is cast in the same piece) being reversed in order to give a better view of the grinding teeth. Vhen the parts are brought together, the mill dress O, Fig. 3, opposes the mill dress M, Fig. 4, and when the wheel M, is revolved, the middle tooth m, Fig. 4, (and its fellow in the opposite side of wheel M) travels between the semicircular and jagged teeth Q, Fig. Il, while` the other teeth m, in Fig. 3, travel in corresponding furrows in the grinding surface, Fig. 4. It will be observed that the semicircular teeth Q, Fig. l, are wanting on the side next the hopper I-I, so that the apples or ears of corn may feed freely into the cavity in which the hooked teeth m, Fig. 3, travel, and the faces of these teeth Q, are

set obliquely, forming a jagged tooth, very armed with cogs or teeth S, and that surface of the wheelis completely set with shelling teeth of the usual form. /Vhen this wheel is brought into place, the cogs S engage with the cogs of wheel F, by which means the shaft D, bevel toothed wheel U, and balance wheel V, are set in motion, The ears of corn are fed into hopper R, and being pressed against wheel U, by a spring e', they are caught by both wheels M and U, and are thus quickly carried downward and shelled, the cobs and shelled corn escaping at the spout Gr. The wheel shaft D, may carry an emery wheel or grinding stone W.

The shelling or the grinding surfaces may be adjusted at pleasure by means of a screw Y, Fig. 2 (which bears against the shaft C) in connection with the screw X.
